Trustix Secure Linux Security Advisory #2004-0043

Package name:      courier-imap, samba, zlib
Summary:           Multiple vulnerabilities
Date:              2004-08-26
Affected versions: Trustix Secure Linux 1.5
                   Trustix Secure Linux 2.0
                   Trustix Secure Linux 2.1
                   Trustix Operating System - Enterprise Server 2

- --------------------------------------------------------------------------
Package description:

  courier-imap:
  Courier-IMAP is an IMAP server for Maildir mailboxes.  This package contains
  the standalone version of the IMAP server that's included in the Courier
  mail server package.  This package is a standalone version for use with
  other mail servers.  Do not install this package if you intend to install the
  full Courier mail server.  Install the Courier package instead.

  samba:
  Samba provides an SMB server which can be used to provide network
  services to SMB (sometimes called "Lan Manager") clients, including
  various versions of MS Windows, OS/2, and other Linux machines.

  zlib:
  The zlib compression library provides in-memory compression and
  decompression functions, including integrity checks of the uncompressed
  data.  This version of the library supports only one compression method
  (deflation), but other algorithms may be added later, which will have
  the same stream interface.  The zlib library is used by many different
  system programs.

Problem description:

  courier-imap:
  Format string vulnerability in the auth_debug function in Courier-IMAP
  1.6.0 to 2.2.1, when login debugging (DEBUG_LOGIN) is enabled, allows
  remote attackers to execute arbitrary code.
  The Common Vulnerabilities and Exposures project (cve.mitre.org) has
  assigned the name CAN-2004-0777 to this issue.

  samba:
  A new samba release (2.2.11) in Trustix Secure Linux 1.5 and 2.0
  fixes crashes in smbd triggered by a Windows XP SP2 client sending a
  FindNextPrintChangeNotify() request without previously issuing
  FindFirstPrintChangeNotify().

  A new samba release (3.0.6) in Trustix Secure Linux 2.1 and Trustix
  Operating System - Enterprise Server 2 fixes a few bugs and memory leaks.
  See also the changelog on 
  <URI:http://us3.samba.org/samba/history/samba-3.0.6.html>

  zlib:
  A bug in zlib 1.2.1 would make it crash on certain invalid input.  This
  problem is believed to have DoS (Denial of Service) potential only.

Action:
  We recommend that all systems with this package installed be upgraded.
  Please note that if you do not need the functionality provided by this
  package, you may want to remove it from your system.
